This paper presents a type-IV wind turbine generator (WTG) model developed in MATLAB/Simulink. An aerodynamic model is used to improve an electromagnetic transient model. This model is further developed by incorporating a single-mass model of the turbine and including generator torque control from an aerodynamic model. The model is validated using field data collected from an actual WTG located in the Scaled Wind Farm Technology (SWiFT) facility. The model takes the nacelle wind speed as an estimate. To ensure the model and the SWiFT WTG field data is compared accurately, the wind speed is estimated using a Kalman filter. Simulation results shows that using a single-mass model instead of a two-mass model for aerodynamic torque, including the generator torque control from SWiFT, estimating wind speed via the Kalman filter and tunning the synchronous generator, accurately represent the generator torque, speed, and power, compared to the SWiFT WTG field data.
